声学性能仿真软件解决方案
针对纯电/混动车型开发的声学性能提升
与传统汽车相比，新车设计尤其是电动车的设计截然不同，其必须满足不断发展的法规要求。声学性能的挑战主要来自于车内声学包对汽车品牌、轻量化以及噪声舒适性的要求。对于纯电及混动车而言，在早期设计阶段对来自电动力总成噪声、进排气噪声、风噪、路噪等噪声源的贡献量进行精确仿真，是预测车内噪声的关键所在。
通过使用ESI的声学性能虚拟试验场，工程师可以全数字化设计消除车内外噪音，从而创造一个开发优秀NVH性能产品的满意流程：从激励源到声辐射，以及通过不同的传递路径再到虚拟测试车辆的声学性能。利用虚拟测试，在第一时间获得合理的新设计方案的同时，也消除用于物理样机NVH分析测试的高昂成本。

模拟外部声学性能
安全问题始终是最重要的。通过创建有效的声学警示音系统，在电动汽车交通场景中保护弱势的参与群体，实现一个没有交通致死事故的世界。另外同时也要满足汽车通过噪声法规要求。
How to achieve an optimal acoustic experience for electric vehicles?
Today, it is possible to detect and solve any exterior and interior acoustics problems upfront in the development cycle, using digital tools that leverage Finite Element Methods (FEM), Ray tracing and more, covering log and high frequencies. Organizations like Audi, Bentley, Nissan, and the US Army are already harnessing the convenience of a digital vehicle test facility.
